1. What is m³ to kWh Gas Conversion?

Definition: This calculator converts gas volume in cubic meters (m³) to energy in kilowatt-hours (kWh) using calorific value and correction factor.

Purpose: It helps utility companies, engineers, and consumers convert gas volume measurements to energy units for billing and energy analysis.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ E_{kWh} = \frac{V_{gas} \times CV \times CF}{3.6} \]

Where:

\( E_{kWh} \) — Energy in kilowatt-hours
\( V_{gas} \) — Gas volume in cubic meters
\( CV \) — Calorific value (MJ/m³, typically ~39)
\( CF \) — Correction factor (typically ~1.02264)
3.6 — Conversion factor from MJ to kWh

Explanation: The formula accounts for the energy content of the gas and standard conditions for temperature and pressure.

3. Importance of Gas Conversion

Details: Accurate conversion is essential for energy billing, comparing fuel costs, and understanding energy consumption.

4. Using the Calculator

Tips: Enter the gas volume in m³, calorific value (default 39 MJ/m³), and correction factor (default 1.02264). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why is the calorific value important?
A: It measures the energy content per unit volume of gas, which varies by gas composition and source.

Q2: What is the correction factor for?
A: It adjusts for temperature and pressure differences from standard conditions (15°C, 1013.25 mbar).

Q3: When would I change the calorific value?
A: If using different gas types (e.g., propane ~93 MJ/m³) or if your supplier provides specific values.

Q4: How accurate is this conversion?
A: Very accurate when using correct CV and CF values from your gas supplier.

Q5: Why divide by 3.6?
A: 1 kWh = 3.6 MJ, so we divide to convert from MJ to kWh.
